People are talking about Gann Angle.... Everyone has his own Story... Look at yellow channels... For me a Gann Angle can be found this way: Log Scale, Connect more and more Trendlines ( also Intratrendlines). =>You find a Degree where most of the Trend lines have the same Angle. Using the Tool Parallel-lines helps me a lot by this.
Not visible on Chart, but maybe will make an education of this: You can do this on both ways Bullish and Bearish Terndlines ( Angles) at same time. "a squaring Point" is then the Scalar, the Interceptions in lines, time and Price. Same angle = there is now Interception of same kind of Trendlines ( Angles)! ( e.g.: Bullsih angles all tend to Alpha 33°, Bearisch one to -45°)
